What is Server Message Block?
SMB is a client-server interaction protocol where clients request a file, and the server provides it to the client. It is now a Windows-based network that gives users to create, modify and delete the shared files, folders, printers within the network. SMB is an application layered protocol that uses TCP Port 445 to communicate. It also provides a herborized intercommunication mechanism to transfer to share the files between the client and the server. With the upgrades of its versions, the services are much more enhanced and effective to use by the users or clients.
What is SMB in IT?
SMB provides an authenticated intercommunication process mechanism to share the files or resources (files, folders, printers) within the server. SMB provides the clients to edit files, delete them, share the files, browse the network, print services, etc., over the network.
What is SMB1 version?
SMB1. SMB1 is very similar to the CIFS protocol that shares the files over a network to access them among the clients in an effective way. SMB was initially introduced to run on top of NetBIOS and TCP/IP interface.
Why is SMB2 better than SMB1.0?
SMB2 has reduced the “chattiness” of SMB1.0 Version file system protocol by reducing the number of commands and subcommands that are used to communicate the system to just nineteen commands. This Version also has a pipeline mechanism that sends an additional service request before the response to a previous request is arrived. This mechanism has improved the performance level, which was lagging in the previous SMB 1.0 version. SMB1.0 was using a 16-bit data size, whereas SMB2.0 is using a higher level of 32 or 64-bit wide storage data fields. This helps store larger file data and communicate the large files over the network in less time.
What are the features of SMB?
As the versions of SMB have increased, the performance level is also increasing. Below are the few important features of SMB: 1 SMB provides an authenticated intercommunication process mechanism to share the files or resources (files, folders, printers) within the server. 2 SMB provides the clients to edit files, delete them, share the files, browse the network, print services, etc., over the network. 3 SMB version 2 has decreased the usage of a number of commands and subcommands used to transfer the file over the network. 4 SMB2 supports symbolic links as an enhancement version to SMB version 1.
What version of SMB2 is supported?
The version SMB2 is supported for Windows Vista 2006, and SMB3 supports Windows 8 and Windows Server 2012. Commands and subcommands are used to transfer a file over the network for which the clients request. In CIFS, the number of commands used was more than a hundred to just transfer a file. But in SMB, it has been reduced to almost nineteen ...
What is SMB authentication?
SMB Authentication Protocol. SMB contains two levels of security checks. They are the user checks and share checks. Share is generally referred to as a file or folder that is requested by the client, directory or a printer service that is to be accessed by the clients over the server.
What is SMB Direct?

Does SMB 3.0 support SMB 3.0?
Both the SMB client and SMB server must support SMB 3.0 to take advantage of the SMB Multichannel functionality. SMB 1.0 and SMB 2.x clients will use a single SMB connection.
Can SMB 1.0 and SMB 2.x be used?
However, SMB 1.0 and SMB 2.x clients won't benefit from the SMB Transparent Failover feature. If the currently accessed cluster node becomes unavailable, or if the administrator makes administrative changes to the clustered file server, the SMB 1.0 or SMB 2.x client will lose the active SMB session and any open handles to the clustered file server. The user or application on the SMB client computer must take corrective action to reestablish connectivity to the clustered file share.
SMB 3.0 support for VSS
This support is a big deal because you can now use VSS to make application-consistent backups of server applications on remote file servers. For example, you could have a Hyper-V host’s guests (virtual machines) on remote files shares.
